Technical Field

[0001] This utility model relates to the field of gantry crane technology, specifically to a movable gantry crane for hoisting in narrow spaces. Background Technology

[0002] A hoisting gantry is typically constructed by a top crossbeam and two side columns, forming a gate-like frame. Lifting equipment, such as an electric hoist, is then installed on the top crossbeam for hoisting. To enhance the stability of the hoisting gantry, bases or diagonal braces are usually installed at the bottom of the two side columns to improve the overall stability of the hoisting gantry.

[0003] However, in existing conventional hoisting gantry structures, the top crossbeam and the two side columns are usually fixedly connected. This means that existing hoisting gantry structures can generally only be used in relatively large spaces. In narrower spaces, existing hoisting gantry structures often cannot be moved to a suitable position for hoisting, and moving the entire hoisting gantry is extremely inconvenient. Based on the above background, the inventors designed a movable gantry for hoisting in narrow spaces, which can solve at least one of the above problems, and thus, this application is filed. Utility Model Content

[0004] The purpose of this application is to provide a movable gantry for hoisting in narrow spaces, solving the problem that existing hoisting gantry frames cannot be adapted to narrow spaces.

[0005] This application provides a movable gantry for hoisting in narrow spaces, including a frame body. The frame body includes a horizontally arranged top beam and a first support part and a second support part, both of which are vertically arranged and rotatably connected to both ends of the top beam. The pivots of the first support part and the second support part are both vertically arranged.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solution of this invention / utility model, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 As shown, this embodiment provides a movable gantry for hoisting in narrow spaces, including a frame 1. The frame 1 includes a horizontally arranged top beam 11, and also includes a first support part 12 and a second support part 13 that are both vertically arranged and rotatably connected to both ends of the top beam 11. The pivots of the first support part 12 and the second support part 13 are both vertically arranged. The volume of the first support portion 12 is larger than that of the second support portion 13; It also includes casters located at the bottom of the first support portion 12.

[0019] This embodiment, by setting a first support part 12 and a second support part 13 respectively rotatably connected to both ends of the top crossbeam 11, and the volume of the first support part 12 is larger than that of the second support part 13, and by setting universal wheels at the bottom of the first support part 12, allows the gantry crane disclosed in this application to not only rotate the first support part 12 and / or the second support part 13 to adapt to narrow and asymmetrical spaces, but also greatly facilitates the movement of the gantry crane by a single person. When moving the gantry crane, one only needs to hold the first support part 12 with one hand and lift the second support part 13 with the other hand to lift it off the ground to adjust and move the position of the entire gantry crane. Therefore, this embodiment, through its asymmetrical design and the rotatable design of the first support part 12 and the second support part 13, can effectively solve the problem that the hoisting gantry cranes in the prior art cannot adapt to narrow spaces.

[0020] In this embodiment, the first support part 12 includes at least three vertically arranged first vertical rods 121, and multiple connecting horizontal rods for connecting the first vertical rods 121 into a whole; The first support part 12 also includes a top connecting rod 123, the two ends of which are fixedly connected to two connecting crossbars respectively; The first support part 12 is rotatably connected to the top crossbeam 11 via a top connecting rod 123; The omnidirectional wheel is detachably mounted on the bottom of the first vertical rod 121; The weight of the first support part 12 is greater than that of the second support part 13, which makes it easier for the operator to lift the second support part 13 when moving the gantry.

[0021] In some embodiments, a plate can be provided on the top of the first support 12, so that the top beam 11 is directly rotatably connected to the center of the plate. In this embodiment, a top connecting rod 123 is provided, and the end of the top beam 11 is rotatably connected to the middle of the top connecting rod 123, which can reduce the weight of the entire first support 12.

[0022] In this embodiment, there are four first vertical rods 121; The multiple connecting crossbar groups 122 are arranged in a layered structure. The multiple connecting crossbar groups 122 are distributed vertically. Each connecting crossbar group 122 includes four connecting crossbars in the horizontal direction. The two ends of each connecting crossbar are fixedly connected to two first vertical bars 121 respectively. In this embodiment, the multiple connecting crossbar groups 122 are arranged in a layered structure, which can make the weight distribution of the entire first support part 12 balanced and avoid the problem of top-heavy or bottom-light.

[0023] In this embodiment, the top crossbeam 11 is rotatably connected to the middle position of the top connecting rod 123, making the support of the first support part 12 on the top crossbeam 11 more stable and avoiding the problem of instability or even tilting of the top crossbeam 11 after bearing load.

[0024] In this embodiment, the second support part 13 includes a vertically arranged second vertical rod 131, the top of which is rotatably connected to the end of the top crossbeam 11 away from the first support part 12.

[0025] In this embodiment, the second support part 13 further includes a bottom crossbar 132 horizontally disposed at the bottom of the second vertical bar 131. The bottom crossbar 132 can improve the support stability of the second support part 13. In this embodiment, there is one bottom crossbar 132. In some embodiments, a bottom crossbar or plate can be used to replace the bottom crossbar 132. In this embodiment, the single bottom crossbar 132 can ensure support stability while making the second support part 13 lightweight enough to facilitate the operator to adjust and move the entire gantry frame.

[0026] In this embodiment, the second support portion 13 further includes two reinforcing diagonal braces respectively disposed on both sides of the second vertical rod 131. One end of each reinforcing diagonal brace is fixedly connected to the second vertical rod 131, and the other end is fixedly connected to the bottom horizontal rod 132. The two reinforcing diagonal braces improve the support stability of the first support portion 12.

[0027] In this embodiment, the bottom of the middle position of the top crossbeam 11 is provided with a hanging lug 111, which facilitates the installation of various lifting equipment, such as electric hoists, which will not be described in detail here.

[0028] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
